IASONAS against its type
Built in 2008, it is 2 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 62,782 gross tonnage it is larger than 61% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The returns for 2019–2025 all give Monrovia as port of registry.
Its 12,260 t of CO₂ for 2025 is 1.5 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 458.0 kg CO₂, 14% above the type median of 403.2 kg. It logged 2,337 hours at sea against a median of 2,030 hours for its type that year. 9.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2020 (15,363 t) and the lowest 2019 (4,238 t). Its efficiency percentile within the type went from 20 in 2019 to 21 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 301 of 1,448 qualifying oil tankers by EEOI, at the 21st percentile. The dashed line is the type median, 7.5; this vessel reported 5.3.
EEOI divides emissions by transport work, which for this vessel and year was 2,330,709,126 tonne-miles over 26,766 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 189.3% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 5.0% while distance sailed rose 9.3%and CO₂ per nautical mile fell 3.9%.That points mainly to how much the vessel sailed, rather than the other.
